Linux
comes ready to use 'out of the box'. All the programs you're likely to
need are included with Linux: just click on the Firefox / Google Chrome
icon and straight away you can access GGi, YouTube, Facebook, Gmail / Yahoo Mail, etc (internet connection needed, obviously!)

Likewise, LibreOffice is included so
you can type a letter, or create a spreadsheet, without having to buy
and install Microsoft Office. You can open and edit MS
Office files and work created in LibreOffice can be opened / used in MS Office by saving it in MS Office format.

Want to watch a DVD or listen to a CD? VLC
Player is there waiting for you to use. Want to edit music, images or videos? Yep, there's programs included.Want to open and read a .pdf
document? Yes, a fast, lightweight .pdf reader is included. No further
software downloads and installs needed.Not only that but
other programs you may want, such as Skype, are freely available from a
repository (*safe* 'app store' of tried and tested programs) directly
accessible through Linux.
